With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13544-43-9,6-(Trifluoromethyl)-1H-indole,as a common compound, the synthetic route is as follows.

In a round-bottomed flask, 1.0 g of 6-trifluorom- ethylindole (5.40 mmol; 1.00 eq) were dissolved in 10 mE of acetone (10.00 mE), 0.68 g of potassium hydroxide (12.15 mmol; 2.25 eq) were added to this dark orange solution and then the mixture was stirred at RT for 15 mm and 672 tE of iodomethan (10.80 mmol; 2.00 eq) were added. The reaction mixture was stirred at RT for 20 h. The reaction medium was then taken up with water and extracted with ethyl acetate. The organic phase was washed once with a saturated NaC1 solution, dried over MgSO4 and concentrated under reduced pressure. The residue was purified by flash chromotography (l3iolage 50 g silica 30 microns adsorption on silica in dichloromethane) using a cyclohexane/ethyl acetate gradient of 99/1 to 90/10. The fractions containing the targeted product were combined and then evaporated under reduced pressure to give 835 mg of 1 -methyl-6-(trifluoromethyl)indole.10575] Yld: 78%. ?H NMR (300 MHz, DMSO-d5) oeppm 3.88 (s, 3H)6.56 (d, J=3.1 Hz, 1H) 7.30 (d, J=8.3 Hz, 1H) 7.57 (d, J=3.0Hz, 1H) 7.74 (d, J=8.3 Hz, 1H) 7.86 (s, 1H).

As the paragraph descriping shows that 13544-43-9 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13544-43-9,6-(Trifluoromethyl)-1H-indole,as a common compound, the synthetic route is as follows.

1-(p-tolylsulfonyl}-6-(trifluoromethyl)indole; 6-Trifluoromethylindole (2.082 g; 10.908 mmol; 1.00 eq.) was dissolved intoluene (30.000 ml; 283.265 mmol; 25.97 eq.). Tetra-n-butylammoniumhydrogensulfat (555.541 mg; 1.636 mmol; 0.15 eq.), NaOH solution 32%(30.000 ml; 324.024 mmol; 29.71 eq.) and toluene-4-sulfonylchloride (3.183 g; 16.362 mmol; 1.50 eq.) were added at ooc. The solution was stirred for 14 h in a thawing ice bath. The reaction mixture was diluted with toluene and water,the organic layer was washed twice with a saturated solution of ammonia and1 x with water. The organic layer was dried over MgS04, filtered andconcentrated under reduced pressure. This gives 4 g (95%) of the titlecompound as a brown solid; HPLC MS (Method G): (M+H) 340; Rt 2.601 min.

The synthetic route of 13544-43-9 has been constantly updated, and we look forward to future research findings.
